The U.S. Army Construcuion Engineering Research Laboratory (CERL), in Champaign, Illinois reports in testing fibrous concrte for use in airfield pavements. The CERL tests were performed at Vicksburg, Mississippi in conjuction with plain concrete pavements studies being conducted at the U.S. Army Waterways Experiment Station in Vicksburg, Mississippi. Both fibrous reinforced and plain concrete pavements were subjected to simulated loadings of the C54 military cargo plane. The fibrous pavements was only half as thick as the regular pavement, but it withstood twice as many load applications and incurred far less damage. When the regular pavement was virtually destroyed, the fibrous pavement still had useful life. Fibrous concrte has remardable durability an strength, yet its composition is simple. It is compsed of cement, finea dn medium grade aggregate, and steel fibers 1 inch long an d16 mils in diameter. The fibers deter flaws in th econcrete from enlarging under load to form visible cracks. By restricting the development of cracks which eventually
